遺伝子(ID):
IL18(3606)
タンパク質の説明:
The protein encoded by this gene is a proinflammatory cytokine that augments natural killer cell activity in spleen cells, and stimulates interferon gamma production in T-helper type I cells. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2011]

研究背景

機能:

A proinflammatory cytokine primarily involved in polarized T-helper 1 (Th1) cell and natural killer (NK) cell immune responses (Probable). Upon binding to IL18R1 and IL18RAP, forms a signaling ternary complex which activates NF-kappa-B, triggering synthesis of inflammatory mediators. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells and natural killer (NK) cells (Probable).

PTMs:

The pro-IL-18 precursor is processed by CASP1 or CASP4 to yield the active form.

細胞の位置付け:

Secreted.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
サブユニット構造:

Forms a ternary complex with ligand-binding receptor subunit IL18R1 and signaling receptor subunit IL18RAP at the plasma membrane. Mature IL18 first binds to IL18R1 forming a low affinity binary complex, which then interacts with IL18RAP to form a high affinity ternary complex that signals inside the cell.

タンパク質ファミリー:

Belongs to the IL-1 family.

FIGURE 3 Ox‐LDL increased ADAM17 and sTIMD4 while decreased mTIMD4 level in macrophages. RAW264.7 cells were treated with ox‐LDL at the indicated concentrations for 24 h (A, D–G) or with 80 μg/mL ox‐LDL for the indicated times (B) or LPS at 1 μg/mL for 24 h (C). After treatment, total cellular proteins, RNA, and treatment mediums were collected. (A–C) Expression of ADAM17, mTIMD4, IL‐6, IL‐10, pro‐IL‐1β, IL‐1β, caspase‐1, and IL‐18 in cells and sTIMD4 in medium was detected by Western blotting (n = 3).
